I believe some people have tried. :(
Apparently H4 bulbs are difficult to make effective with the smaller diameter lens.
Explanation is here: https://www.candlepowerforums.com/threads/who-has-the-best-sealed-beams.288782/
Also See 5.75" H5006 sealed beam & H4 Photometrics at Dan Stern Lighting
Stern doesn't show the "vision plus" on that page but between him and 'Virgil' on Candlepower forums, if there was something reasonably good, they'd know.

For the High Beams using H1 bulbs in Hella's "Vision Plus" H1 might be a reasonably safe bet.
However refering back to now older posts, in 2014 Stern was recommend the Bi-focal H1

We can ask if @slantsixdan has something new to add

All that said, @cruiser still needs to find the problem.
